This is a magical race, the Yanlang, living in a world made up of fragments from countless planes. They feed on sadness, fear and all other negative emotions, which means...
Their world is free of negative emotions such as sadness and fear.
Do you think such a world is beautiful? I think that since they have no sadness, no fear, no negative emotions, then their world must only have beautiful emotions such as joy and happiness...
It's too naive...
There are no negative emotions in their world, so in contrast, they have no basis for comparison. In other words...
Their world has no emotions at all.
"What do you think Yanlang is?" Such a voice came from mid-air.
"Gods," he replied expressionlessly, without any emotion. He didn't even have the concept of emotions. "Humans, that's what they call us."
"After all, doesn't it mean that you don't even know what you are?" The voice was full of ridicule and disdain, "How can a real god be a guy like you who doesn't even know what emotions are... I said, do you want to know what emotions are?"
"What is emotion..."
"Then start the experience from your own cage~"
Thirteen cages.
Thirteen planes.
Thirteen tragedies.
This is a mirror,
I'll show you the whole truth.
